20699-85-8, The synthetic route of 20699-85-8 has been constantly updated, and we look forward to future research findings.

20699-85-8, Methyl 5-aminobenzo[b]thiophene-2-carboxylate is a benzothiophene compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated

Compound 61 (300 mg, 1.448 mmol) was dissolved in DMF (4.83 mL). Mel (109 pL, 1.737 mmol) was added, followed by K2C03 (300 mg, 2.171 mmol) and the reaction was stirred at rt overnight. Water was added to the reaction mixture to precipitate the product. The resulting slurry was filtered to obtain a brown solid. The crude product was purified by silica gel chromatography (10% to 100% EtOAc/hexanes) to obtain compound 64 as an orange solid (95 mg, 0.434 mmol, 30% yield). UPLCMS = 1.32 min (2.5 min method). Mass observed (ESI+): 222.4 (M+H).
